When loading 'deoplete.nvim' for the 2nd time during InsertEnter
manually, the `s:dobufread` (or `s:lod` itself) prevents it to work
properly - likely because the plugin gets resourced.
Maybe there could be a way to force this (and reload plugins always),
but by default it seems to make sense to skip already loaded plugins.
Checking out a branch or tag may not succeed if there is a path entry
with the same name. This commit appends -- to git checkout commands to
clarify that we're not referring to a file or a directory.
Close#602
Now `:PlugInstall!` and `:PlugUpdate!` forces to update submodules.
`:PlugInstall!` now also checks out to new specified branch, tag, or
commit.
Also added tests for changing branch, tag, or commit.
This commit extracts duplicate logic out of three installers.
Pros.
- Better maintainability
- Easier to add/extend the features
- Fixes a bug when 'commit' option is used, submodules are updated
before the designated commit is checked out
Cons.
- The whole process takes slightly longer due to lost parallelism after pull
- Especially, submodule updates are not parallelized
- However, this shouldn't matter much in practice as there are few
plugins that heavily rely on submodules
- The output file is no longer executable but a source-able vim script
- PlugSnapshot FILENAME to prompt the user if the file already exists
- Add PlugSnapshot! FILENAME variant to force overwrite existing file
- Apply -complete=file option to PlugSnapshot command
The older documentation of vim-plug suggested that the second string
parameter to Plug command was for both branches and tags. But we've
realized that tags and branches are not interchangeable (#174), and it
is now recommended that the user explicitly specify whether it's a
branch or a tag. The now-undocumented second parameter is currently for
branches, but I'd like to change it for tags, as the use of tags are
much more common.
